To increase accuracy of predicting the performance of a tire on a snowy road.SOLUTION: The present invention relates to a method for simulating a tire which reproduces the behavior of a tire running on a snowy surface. The method includes the steps of: setting a tire model 50 formed by a finite number of elements on which a numerical analysis can be done; setting an Euler element model 54 including a snow model 56 in which a water film 58 is provided on at least a part of a snowy surface as an analysis model containing snow in the inside; and performing a dynamic analysis by rolling the tire model 50 on the snow model 56.SELECTED DRAWING: Figure 3

    【課題】雪路面でのタイヤ性能の予測精度を向上する。【解決手段】雪路面を走行するタイヤの挙動を再現するタイヤのシミュレーション方法である。同方法は、数値解析が可能な有限個の要素でモデル化したタイヤモデル50を設定するステップと、内部に雪を配置した解析モデルとして雪面の少なくとも一部に水膜58が設けられた雪モデル56を含むオイラー要素モデル54を設定するステップと、タイヤモデル50を雪モデル56上で転動させて動的解析を行うステップとを含む。【選択図】図3
